Configuring Remote O&M for an MRS Cluster

If you encounter any issues while using a cluster and require assistance from Huawei Cloud support personnel, you can first contact them. Then, you can authorize them to access your machine through the O&M authorization function to locate the fault. Alternatively, you can provide Huawei Cloud support personnel with logs from a specific time period using the log sharing function to help them locate the fault.
